What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationTSB: Pre-Delivery Service (PDS) is a critical step in satisfying our new car customers. Customer feedback indicates the following areas deserve special attention when performing PDS: ? Careful inspection for paint chips/scratches and body dents/dings. ? Proper operation of electrical accessories (including interior light, clock, and radio reset). ? Interior cleanliness. ? Proper function of mechanical systems. Customer retention and proper maintenance of vehicles are and have always been a major focus for Lexus. To help remind customers that regular service is essential to the proper maintenance of the vehicle, dealers are required to input their dealer information and set the service reminder on the Navigation Screen before delivery. By doing this, customers will be reminded to return to your dealership for service. (See Page 2 of the IS 300/350/500 PDS Check Sheet ?Set Dealer and Service Reminder.?) This bulletin contains the PDS procedures that apply specifically to the 2024 model year IS 300, IS 350 and IS 500. To properly perform a complete PDS, you must complete all procedures contained in this TSB as well as the IS 300/350/500 PDS Check Sheet. In addition, if the vehicle is stored for over 30 days, be sure to follow Long-Term Vehicle Storage Guidelines.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lexus L-SB-0049-23 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the L-SB-0049-23 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Toyota warranty extension on file lists the ones Toyota has filed.
Which vehicles does L-SB-0049-23 cover?
The manufacturer filed it against 1 model year: 2024 Lexus IS. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
